What is Google’s new reCAPTCHA
Google’s new reCAPTCHA replaces older CAPTCHA models by asking users to check a box instead of looking at a distorted image and filling in the text/numbers. It is a single click solution to the CAPTCHA problem – when it works.
The new reCAPTCHA will fall back to older CAPTCHA models if Google’s “risk analysis engine” thinks you might be a bot.
What it does?
The new reCAPTCHA is a widget utilizing Google’s reCAPTCHA API (version 2.0) in order order to verify people are not bots. It works by passing along the user’s behaviors to Google’s “risk analysis engine” before, during, and after a user checks a box so that Google can determine whether a single-click solution is justified. If not, the user will be presented the traditional reCAPTCHA.
What will it do for you?
It will reduce spam.
reCAPTCHA reports the daily pass and fail stats in an admin console, and will also show how many noCAPTCHAs were rendered per day as well as a site spam index chart.
It will likely infuriate users using assistive devices.
What are its weaknesses?
Google’s new reCAPTCHA is still being evaluated by the accessibility community and those using assistive devices, so there’s no consensus on its performance. Within the accessibility community there’s not a lot of love for CAPTCHAs, and thus far Google’s new reCAPTCHA has done very little to change this. The following are documented and/or commonly reported problems –
- regularly falling back to traditional CAPTCHA when using assistive devices
- keyboard tabbing issues
- selecting images with a keyboard
- iframe/title attributes when using JAWS (Firefox/IE)
- audio challenges and typing into forms
- implementations can alter
The API key pair is unique to the domains and first-level subdomains, however, I’m not sure how this impact complex, federated “sites”.
How will it benefit you?
For those not using assistive devices, as long as Google doesn’t think the user is a bot, Google’s new reCAPTCHA is simple and elegant, and will likely reduce spam without negatively affecting usability.
For those using assistive devices, Google’s new reCAPTCHA presents the same accessibility issues limiting traditional CAPTCHAS, as well as an additional step (the failed noCAPTCHA reCAPTCHA stop).
